Revert "Revert "ART: Support interpreter switching in x86 mterp""
Fixes the invoke template. Previously, it was permitting
an interpreter switch *before* advancing the Dalvik PC.
This meant that on a switch, the invoke would be interpreted
twice.
This reverts commit a14bf4460268064e0adc4bb210d237209be33eaf.
